I've been considering the possibility of having the master resolve
the situation automatically without waiting for a recording by having
the affected backends write out a random-sized 0-10 megabyte file
then redoing the space calculations, but it hasn't bugged me enough
to write a patch yet.  Another possibility is to just assume they are
not the same if they are near-empty and of equal size.  This is the
easiest thing to do because it's a simple if statement in the current
code.  Again, patches welcome if someone wants to take a look.  Worst
case is that we record multiple shows to the same filesystem without
knowing if the same empty filesystem is referenced multiple times.
